Fig. 1 and 2 show a cable jacket tube 100 according to a preferred embodiment of the present utility model, the cable jacket tube 100 having a cylindrical structure including an outer thermoplastic resin layer 110, an inner thermoplastic resin layer 120, and a continuous fiber reinforced thermoplastic resin structure 130. The outer thermoplastic resin layer 110 is disposed at the outermost side of the cable jacket tube 100; the thermoplastic resin layer 120 is disposed at the innermost side of the cable jacket tube 100; the continuous fiber-reinforced thermoplastic resin structure 130 is disposed between the outer thermoplastic resin layer 110 and the inner thermoplastic resin layer 120, and the continuous fibers in the continuous fiber-reinforced thermoplastic resin structure 130 are configured as a three-dimensional woven mesh structure extending in the axial direction of the cable jacket tube 100.

As shown in fig. 1 and 2, the outer thermoplastic resin layer 110 and the inner thermoplastic resin layer 120 may each have a cylindrical structure. Preferably, the outer thermoplastic resin layer 110 and the inner thermoplastic resin layer 120 are coaxially disposed. It is understood that the outer thermoplastic resin layer 110 and the inner thermoplastic resin layer 120 each comprise a thermoplastic resin. Illustratively, the outer thermoplastic resin layer 110 may include a first thermoplastic resin, and the inner thermoplastic resin layer 120 may include a second thermoplastic resin, which may be the same or different. It is understood that the continuous fiber-reinforced thermoplastic resin structure 130 includes continuous fibers and a thermoplastic resin, and in particular, the continuous fiber-reinforced thermoplastic resin structure 130 includes a three-dimensional woven mesh structure composed of continuous fibers and a third thermoplastic resin, which may be the same as or different from the first thermoplastic resin and/or the thermoplastic resin. The thermoplastic resin can be repeatedly heated, softened, melted, cooled and hardened, so that the thermoplastic resin in the waste cable sheath tube can be separated from the continuous fibers by a simple heating method, and the waste cable sheath tube can be recycled, thereby saving energy, reducing emission and reducing environmental pollution.

The three-dimensional woven mesh structure in the continuous fiber-reinforced thermoplastic resin structure 130 is composed of continuous fiber bundles 131, and a plurality of continuous fiber monofilaments are bundled to form the continuous fiber bundles 131. Alternatively, the continuous fiber bundles 131 may be previously combined with the third thermoplastic resin to form a composite material bundle and then a braiding and winding process may be used to form a three-dimensional braided mesh structure, or may be previously combined with the third thermoplastic resin to form a composite material, and the composite material may be prepared by a combination process such as an impregnation method. The continuous fibers extend at least in the axial and radial directions of the cable jacket 100. Optionally, the continuous fibers also extend at least in the circumferential direction of the cable jacket tube 100. Optionally, the continuous fibers also extend in directions intersecting both the axial and radial directions. Preferably, the continuous fibers are uniformly arranged in the circumferential direction relative to the axial direction, and the three-dimensional woven mesh structure is an axisymmetric structure or a centrosymmetric structure. Thus, the continuous fibers extend in multiple directions to provide reinforcement in all directions, and the cable jacket tube 100 of the present application not only has good physical properties in all directions, such as high axial tensile strength, high radial compressive strength, and the like, but also has relatively uniform physical properties in all directions.

Optionally, each continuous fiber bundle 131 comprises 10-100 continuous fiber filaments. Alternatively, the diameter of the continuous fiber filaments is 0.06mm to 0.09mm. Preferably, the diameter of the continuous fiber filaments is 0.075mm. It will be appreciated that the number of continuous fiber filaments and the diameter of the continuous fiber filaments contained in the continuous fiber bundle 131 can be flexibly selected according to actual production conditions and use requirements.

As shown in fig. 2, the thickness of the continuous fiber-reinforced thermoplastic resin structure 130 is greater than the thickness of the outer thermoplastic resin layer 110 and the inner thermoplastic resin layer 120. Of course, the thicknesses of the continuous fiber-reinforced thermoplastic resin structure 130, the outer thermoplastic resin layer 110, and the inner thermoplastic resin layer 120 may be arbitrarily set if needed/desired.

The "thickness" described in the present utility model refers to a dimension in the radial direction of the cable jacket tube.
